As the builder of this website, it's important to make it responsive, working equally well on desktop computers, tablets, and mobile devices. The second aspect is loading speed which is why my photos aren't huge. Images can slow loading considerably. To test if I've been successful I used Google's Page Speed Insights measurement tool. As you can see below I have screenshots of the results.
Of course, your connection plays a big part as well, a slow connection affects these results. ASs time allows I'll work towards getting these numbers higher.
